8-Foot-Long Bull Shark Pulled from Potomac River

Think sharks live only in the ocean? An 8-foot-long (2.4 meters) bull shark was pulled from the Potomac River, along the mid-Atlantic coast of the United States, by a group of Maryland fishermen yesterday (Sept. 3). Sharks do roam the open sea, but certain species, including the bull shark, also live in brackish (low-salinity) water and freshwater.
